ABSTRACT:
An optical trim mechanism is provided for embodiment in the exposure control system of a photographic camera apparatus wherein the output response of the exposure control system is determined by both the photographic scene light reaching the photographic camera as well as the focused distance from the photographic camera to the subject to be photographed. The trim mechanism provides the photographer with a degree of overriding personal control through which he may simultaneously vary the amount of scene light reaching the exposure control system while at the same time varying the output response of the exposure control system as determined by the focused distance from camera to subject.
